Abstract :
It is demonstrated that amplifiers with more than a decade bandwidth that have very low nonlinearity as well as low quiescent power and relatively high gain can be designed by combining the negative-feedback technique and the cascade-compensation technique. The potential of the design strategy is demonstrated in connection with the development of a three-stage amplifier with bipolar transistors.<>
